Start Using Yaml Files
and here is my journey of living with one of the huge libraries ever. Libpg.h though the header file of the libPg is enough to see the available procedures but still you need to give more hints and make it easier to recap the functionality or notes for a specific function. I started to write YAML files for each function and then connected these files in a UML representation you can actually do similar thing in your local machine with yml2dot and then olaaa you got a visualization of your documentation.

App init and graceful watch lib recommendations ?
For configuration, I like Koanf.
-
Two ways to provide configuration: command-line, yaml file.
Of course. You should always use a good config package. caarlos0/env is okay but https://github.com/knadh/koanf is a better all around solution imo.

Golang equivalent of Python’s click (CLT framework)
You can also use Viper with urfave/cli, or you can replace Viper with knadh/koanf, which I personally prefer.

Viper – Go Configuration with Fangs
Use viper with care. It has some dangerous fundamental flaws [1]. We got bitten hard, submitted a PR [2] and followed up for a year and a half to no avail, before I went ahead and reinvented the wheel and wrote koanf (plug), specifically to avoid viper's flaws.
Most importantly:
- Breaks JSON, YAML, TOML etc. language specs by forcibly lowercasing all keys internally. Dangerous because it can silently merge differently cased config keys into lowercase.
- Hard codes big unnecessary dependencies into the core, significantly bloating build sizes. No separation or abstraction.

Extracting embedded files
It's not hard to a) look for a key in an environment variable b) accept a key as a parameter c) load a key from a file d) all of the above with something like koanf

Came across this the other day https://github.com/knadh/koanf as an alternative to Viper.
